Application of the principle of adjustable magnetic field) popup.stage_title Head Milman Yulii Viktorovich, Доктор фізико-математичних наук Registration Date 01-02-2013 Organization Frantzevich Insitute for Materials Science Problems of the Ukranian National Academy of Sciences popup.description2 There were be elaborated a 4 types of magnetic systems for well magnetic lifting devices with adjustable magnetic field (WMLDA). On the base of most optimal construction in the form of two semi-cylindrical magnetic circuits in the nonmagnetic cup with magnets between them the model of magnetic system for the use in the well by diameter of 103 mm was manufactured and tested on carrying capacity. Test on the carrying capacity of the magnetic system with the permanent magnets based on Nd-Fe-B system allows to reach the break effort of 456.5 кgf, in the position "switch off" - 28.8 kgf.
